slide2. 01 Motivation Identify the points where these TSN queuing mechanisms do not meet the requirements and need to be enhanced, providing reference information for new queuing mechanisms.
Verify the rationality and necessity of requirements through evaluation, in order to clarify and improve the requirements draft.
Use the requirement draft to evaluate the new proposed queuing mechanisms.<br>
slide3. 03 TAS Evaluation TAS (Time-Aware Shaper), refer to IEEE 802.1Qbv<br>
slide4. 02 CBS Evaluation [1] Latency and Backlog Bounds in Time-Sensitive Networking with Credit Based Shapers and Asynchronous Traffic Shaping (https://ieeexplore.ieee.org/document/8493026/) CBS (Credit-Based Shaper), refer to IEEE 802.1Qav<br>
slide5. 05 ATS Evaluation ATS (Asynchronous Traffic Shaping), refer to IEEE 802.1Qcr<br>
slide6. 04 CQF Evaluation CQF (Cyclic Queuing and Forwarding), refer to IEEE 802.1Qch<br>
slide7. Comments and Questions Sections 3.3 and 3.4 in the requirements draft both mention considerations about flow aggregation. From a correlation perspective, it is recommended to merge this portion of section 3.3 into section 3.4.
How to understand the "high utilization" mentioned in section 3.4?
“high utilization” may include two aspects:
Allocate a portion of the bandwidth from the total bandwidth for deterministic flows, and the unused portion can be used by BE flows;
Allocate a portion of the bandwidth from the total bandwidth for deterministic flows, and can be utilized sufficiently by deterministic flows as much as possible;
Is it one of the two or both? 06<br>
